Fix ACL Behavior in ClickHouse-Keeper for Consistency with ZooKeeper

Official CH changelog text
Fix ACL with explicit digit hash in clickhouse-keeper: now the behavior consistent with ZooKeeper and generated digest is always accepted. #33249 (小路). #33246.
Fixed ACL handling in clickhouse-keeper to support explicit digit hashes, ensuring behavior consistency with ZooKeeper and that generated digests are always accepted.

Why it matters

This fix addresses inconsistencies in access control list (ACL) processing within clickhouse-keeper where explicit digit hashes were not properly handled. By aligning the behavior with ZooKeeper and accepting generated digests unconditionally, it improves security and reliability of ACL enforcement.

How to use it

Users benefit from this fix automatically after upgrading to the version containing this patch. No additional configuration or manual intervention is required as the ACL behavior is corrected internally.
